Requirements and Suggestions for module installation:
A) The installation surface of the module shall be smooth without scratches, bumps and sundries;
B) When installing the module to the heat sink, gently remove the oxide layer on the surface of the heat sink with fine sandpaper, wipe the surface of the heat sink with anhydrous , and then evenly apply a thin layer of heat-conducting gel on the contact surface of the copper base plate and the heat sink to make the contact good and reduce the thermal resistance;
C) When fastening the module on the heat sink surface, use M5 or M6 flat batten and spring washer, and fasten the screw with (5+1)Nm force distance;
D) The wiring of the main electrode of the module shall be copper strip with smooth, flat and sufficient contact surface. The contact must be good. The tightening moment of force shall be: if M5 screws are used, the moment of force shall be (3) Nm; If M6 screws are used, the moment of force is (5+1)Nm. If M8 screws are used, the moment of force is (9+1) Nm.
